PLASTIC Instrument Installed

STEREO technicians at APL install the PLASTIC instrument onto Observatory "A" (the one that will be placed "ahead" of Earth in its orbit around the sun).

The PLASTIC (PLAsma and SupraThermal Ion Composition) instrument is slated to study coronal-solar wind and solar wind-heliospheric processes. PLASTIC will provide in situ plasma characteristics of protons, alpha particles and heavy ions. It will supply key diagnostic measurements of mass and charge state composition of heavy ions and will characterize the coronal mass ejection plasma from ambient solar wind plasma. The University of New Hampshire's Antoinette Galvin is the principal investigator for PLASTIC.
